Putting this earthquake in context

An earthquake record can change after the first automatic publication as additional stations contribute data and analysts refine the solution.

Interpret the numbers

Magnitude, depth, felt reports and status describe different parts of the event. None of them alone predicts the consequences for a specific city.

Important limits

If the earthquake creates a safety concern, follow local authorities and official warning channels rather than relying on a public data website.
